Title
(DE) HOCHTEMPERATURDICHTUNG MIT KLEMMPROFIL
(EN) HIGH-TEMPERATURE SEAL HAVING A CLAMPING PROFILE
(FR) JOINT D'ÉTANCHÉITÉ HAUTE TEMPÉRATURE À PROFIL DE SERRAGE
Abstract
(DE)
Die Erfindung betrifft eine Dichtung (01) zur Abdichtung eines Spaltes (09) in einem Verbrennungsanordnung einer Gasturbine. Dabei wird die Dichtung (01) gebildet von einem L-förmigen Winkelprofil und einem Klammerprofil. Beide Profile weisen gegenüberliegend eine Eingriffsflanke zur Befestigung in einer Dichtungsnut und eine aneinander anliegende Dichtungsflanke auf. Das Klammerprofil umfasst weiterhin einen der zugehörigen Dichtungsflanke gegenüberliegenden, ebenfalls an der Dichtungsflanke des Winkelprofils anliegenden Halteabschnitt und einen die Dichtungsflanke mit dem Halteabschnitt verbindenden Klemmabschnitt.
(EN)
The invention relates to a seal (01) for sealing a gap (09) in a combustion arrangement of a gas turbine. The seal (01) is formed by a L-shaped angle profile and a clamping profile. Both profiles have on the opposite side an engagement flank for fastening in a sealing groove and a sealing flank bearing against one another. The clamping profile further comprises a holding portion, which is located opposite the associated sealing flank and also bears against the sealing flank of the angle profile, and a clamping portion connecting the sealing flank to the holding portion.
(FR)
L'invention concerne un joint d'étanchéité (01) destiné à étanchéifier un espace (09) dans un agencement de combustion d'une turbine à gaz. Le joint d'étanchéité (01) est constitué d'un profil d'angle en forme de L et d'un profil de serrage. Les deux profils présentent sur le côté opposé un flanc d'engagement destiné à être fixé dans une rainure d'étanchéité et un flanc d'étanchéité s'appuyant l'un contre l'autre. Le profil de serrage comprend en outre une partie de maintien, qui est située à l'opposé du flanc d'étanchéité associé et qui s'appuie également contre le flanc d'étanchéité du profil d'angle, et une partie de serrage reliant le flanc d'étanchéité à la partie de maintien.
